Trump’s super PAC has helped pay his legal bills. That could soon come to an end.

A PAC controlled by former President Donald Trump that spent tens of millions of dollars on his and his allies’ legal bills could run out of cash after spending nearly $3.7 million on legal fees in March.

Save America, Trump’s leadership PAC, has now spent $59.5 million on legal advice since the start of 2023. The company also incurred $886,000 in new legal debt in March, according to a report filed with the Federal Election Commission late Saturday. More than $1.1 million of the March spending went to two companies representing Trump in his criminal hush-money trial in New York.

The total spent on legal fees for Save America was almost as high as Trump’s campaign committee spent in the month of March, highlighting how legal troubles have sucked up money from his political operation. Trump’s official campaign committee spent just over $3.7 million in March, with travel, followed by payroll, taking up the largest spending categories.

That total is minuscule compared to the more than $29 million President Joe Biden’s campaign spent in March, when the incumbent president launched a major advertising campaign.

Save America, Trump’s leading PAC, was able to stay negative in March thanks to another $5 million refund in March from Make America Great Again Inc., the Trump-backed super PAC. The super PAC has transferred $5 million to the leadership PAC every month since last July, with less regular transfers before then.

The leadership PAC initially seeded the super PAC with $60 million before announcing his candidacy. Now MAGA Inc. returning only $2.75 million to Save America, raising questions about whether Save America will continue to be the vehicle to fund legal bills in several Trump-related cases.

The lead PAC had just over $4 million in cash on hand at the end of March. It can still raise money from donors and has previously received money through one of Trump’s joint fundraising committees, although such transfers have been rare in recent months. That source may be further cut off in the future: Since early April, Trump has been sending fundraising emails primarily on behalf of a new joint fundraising committee, the Trump National Committee, which raises money only for his campaign and the Republican National Committee.

The RNC reported its best fundraising month yet in March, raising $20 million, about half of which came from another Trump-affiliated joint fundraising committee. However, the party committee spent $10 million, leaving $21 million in cash, less than half of the $45 million the Democratic National Committee had in the bank at the end of March.

Among the RNC’s expenses in March was $118,000 paid to former chair Ronna McDaniel on March 6, two days before she left the committee. Representatives for McDaniel and the RNC did not immediately return a request for comment on the payment.

MAGA Inc., the pro-Trump super PAC that funds Save America, continued to rake in cash in March, with $14 million raised led by huge donations from high-profile GOP donors. Linda McMahon, the former WWE CEO who led the Small Business Administration under Trump, donated $5 million to the super PAC, while Nevada real estate mogul Robert Bigelow donated more than $4 million. Most of these funds cannot go to Save America because MAGA Inc. is limited in what it can transfer based on what Save America previously gave to the super PAC during the 2022 cycle.
